Adafruit ESP32-S3 Feather with 4MB Flash 2MB PSRAM - STEMMA QT / Qwiic

The Adafruit ESP32-S3 Feather with 4MB Flash 2MB PSRAM - STEMMA QT / Qwiic is a compact and powerful Wi-Fi + Bluetooth LE development board built around Espressif’s advanced ESP32-S3 dual-core processor. Designed in Adafruit’s popular Feather form factor, this board combines native USB support, wireless connectivity, battery charging, and STEMMA QT/Qwiic compatibility, making it ideal for IoT, wearable, automation, sensor, and USB-device projects.

Powered by a dual-core 240MHz ESP32-S3 processor, the board includes 4MB Flash memory and 2MB PSRAM for handling larger buffers, graphics, networking, and CircuitPython applications efficiently. Native USB functionality allows the board to emulate devices such as keyboards, mice, MIDI controllers, and USB serial devices without requiring an external USB-to-UART chip.

The integrated STEMMA QT / Qwiic connector enables plug-and-play interfacing with a wide range of I2C sensors, displays, and peripherals without soldering. Additional features include USB Type-C connectivity, LiPo battery charging, battery monitoring, NeoPixel status LED, deep sleep low-power capability, and compatibility with Arduino, CircuitPython, and ESP-IDF development environments.
